[ACS Macro Lett.] Lewis Pair-Mediated Surface-Initiated Polymerization
We present the first example of surface-initiated polymerization mediated by Lewis pairs for the synthesis of polymer brushes on planar substrates. The method enables the rapid grafting polymerization from the self-assembled monolayer or surface-attached macroinitiators, furnishing linear polymer brushes and bottle-brush brushes. Both homopolyester and block copolyester brushes can be synthesize...

Effect of a Lewis Acid Catalyst on the Performance of HDPE/BFR/GNPs Composites
Brominated flame-retarded high-density polyethylene (HDPE) composites containing graphene nanoplatelets (GNPs) were prepared via melt blending. A Lewis acid catalyst, aluminium chloride (AlCl3), was adopted to initiate the Friedel-Crafts reaction, which contributed to the good dispersion of GNPs and improvement of interfacial interaction. Scanning electron microscopy (SEM) showed that the size of ...

Highly Efficient One-Pot Synthesis of COS-Based Block Copolymers by Using Organic Lewis Pairs
关键字:metal-free Lewis pairs,poly(monothiocarbonate) block copolymer,carbonyl sulfide,immortal polymerization
A one-pot synthesis of block copolymer with regioregular poly(monothiocarbonate) block is described via metal-free catalysis. Lewis bases such as guanidine, quaternary onium salts, and Lewis acid triethyl borane (TEB) were equivalently combined and used as the catalysts. By using polyethylene glycol (PEG) as the macromolecular chain transfer agent (CTA), narrow polydispersity block copolym...

ATOM TRANSFER RADICAL POLYMERIZATION OF METHYL METHACRYLATE INITIATED BY SEC-BUTYL CHLORINE IN THE PRESENCE OF LEWIS ACID
关键字:ATOM,TRANSFER,RADICAL,POLYMERIZATION,METHYL,METHACRYLATE,INITIATED,SEC,BUTYL,CHLORINE,THE,PRESENCE,LEWIS,ACID,
In our previous work [1], the atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) initiated by sec-butyl chlorine (SBC) in the presence of aluminium trichloride (AlCl3) using FeCl2/(PPh3)4 as catalyst was conducted.

Synthesis of optically active (s)-n-(2-hydroxy-1-phenylethyl) methacrylamide and its radical polymerization in the presence of lewis acids
Preparation of stereoregular polymers is an important goal for polymer science and industry because the property and function of vinyl polymers are significantly influenced by their stereoregularity.
